C помощью быстродействующего аналого-цифрового преобразователя (дигитайзера) Caen N6720 сложные аппаратные части установки заменены программным кодом, сформирован канал совпадений в памяти компьютера. Использование дигитайзера позволило значительно упростить создание установки с цифровым каналом совпадений. Исследованы характеристики созданной установки. Точность измерения активности радионуклидов проверена в сравнительных измерениях с государственным первичным эталоном. Получена хорошая согласованность результатов измерения активности с помощью созданной установки и государственного первичного эталона.</p></abstract><trans-abstract xml:lang="en"><p>The results of development of installation for activity measurement by method of 4π(α,β)-γ coincidence are considered. By usage of the high-acting analog-digital converter Caen N6720 digitizer the complex hardware parts of installation were replaced by the program code, and the coincidence channel in the computer memory was formed. Using the Caen digitizer allowed to simplify considerably development of the installation with a digital coincidence channel.  The characterictics of the installation were investigated. The accuracy of radionuclide activity measurements was verified by comparative measurements with the State primary measurement stanbard. The acceptable consistency of the measurement results was obtained.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>активность</kwd><kwd>метод совпадений</kwd><kwd>абсолютный метод измерения</kwd><kwd>мертвое время детектора</kwd><kwd>activity</kwd><kwd>coincidence method</kwd><kwd>absolute measurement method</kwd><kwd>detector`s dead time</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Campion P.
